January 2001 in “Bioscience Biotechnology and Biochemistry” This study found that partial protein extraction from keratinized tissues, such as hair and nails, reveals protein patterns distinct from whole protein extracts, including the presence of ubiquitin.
September 1989 in “PubMed” This study reported detailed three-dimensional ultrastructural observations of human hair and hair follicles using a modified preparation method, including morphological differences in hair bulb cell layers and surface projections on root sheath cells.

August 2008 in “Journal of Forensic Sciences” This study used electron microscopy to characterize tissues on telogen hair roots, finding that tissue quality, including nucleated and nonnucleated epithelial cells, may play a crucial role in DNA typing for forensic analysis.
May 2022 in “Голова и шея.” In this pilot study, researchers observed that low-intensity laser radiation at 445±40 nm increased the temperature of gingival tissues in Wistar rats by 8.37°C without exceeding the safety threshold, suggesting potential for clinical trials.

January 1993 in “DNA sequence” This study sequenced a related gene to KRT2.9 called KRT2.13, which encodes a type II keratin protein not expressed in the hair follicle, and found significant sequence homology suggesting possible gene conversion or conservation of functional sequences.
